Eminem and Rihanna performed their hit single “The Monster” at the MTV Movie Awards this weekend for the first time live. Soon, they’ll perform the hit nightly on their six-night, three-city “Monster” tour in August.

Rolling Stone notes that Rihanna opened the song, while Eminem “over[came] slight technical difficulties to perform a guttural, raucous version.” They were backed by a live band.

Before the awards show, both Eminem and Rihanna posted a photo of themselves in rehearsal to their Instagrams.

“Me with the one and only @badgalriri at rehearsals for the MTV Movie Awards. Tune in tonight at 9/8c,” wrote Eminem.

“TONIGHT NAVY! @Eminem and I are performing #TheMonstER on the @MTV #MovieAwards. Be there at 9/8c,” wrote Rihanna.

Eminem and Rihanna will perform “The Monster” – along with their duets “Love The Way You Lie,” “Love The Way You Lie (Part II)” and “Numb” – in New Jersey, Los Angeles and Detroit during their mini-tour in August. They will perform at Los Angeles’ Rose Bowl on August 7 and 8, at New Jersey’s MetLife Stadium on August 16 and 17 and at Detroit’s Comerica Park on August 22 and 23.

Eminem previously told MTV what makes the pair so compatible.

"I thought it would be a good idea to have her on ['Monster'] because I think people look at us like we're both a little nuts. That's one of the things that I was telling her in making the record: I think that people look at us a little crazy," Eminem said.

"As soon as I got the beat I just heard her on it. I wanted to make sure that I had it finished first to be able to present to her, but once I had the rhymes done, I sent it to her."
